Weird issues. Please help shed light

No more uber for me

 

You’d take your chances in a 500k mile taxi instead ?

 

I don't know which would be better, can't explain it.

it's like a riddle.

hotel charges 3 guests $10 for each night. guests pay $30 and then hotel realize it's a mistake and it's only $10 for all 3 guests. So each guest gets back $6 = $18 with $2 to a tip jar. Essentially Guests only paid $4 each x 3 = $12 + $2 tip jar money = $14 total. What happened to the $30 bucks?

Can't be explained

 

A lot of moving parts for sure.

That’s what the prey on.

As long as it is single or double digits, I’m less inclined to worry though .

 

OP, I think what they are saying it is not safe to drive your car with the ABS and Brake lights on. That is certainly my opinion. I believe the best advice we can give you is either A) get a copy of Techstream to find out what sub-codes are associated with the generic codes your braking system ECU is throwing, or B) take it to a Toyota dealer to get a proper diagnosis. If the ABS actuator has indeed failed, that is not something to take lightly.

 

All riddles and jokes aside, this car is not safe to carry any passengers at the moment. Safety first! You should go and get it checked out.

Many code readers cannot read all the codes on a Prius, you must have a Prius capable code reader. That will give you a true reading of what's wrong with the car.

If you're getting codes that point to many different unrelated things, then you should check the health of the 12v battery. If the battery voltage is too low, it'll give you all kinds of strange errors.

 

Honestly it sounds like a combination of things. First off, you need a new hybrid battery. You already know this. Reconditioning is useless. You have the best case scenario for a reconditioned battery as your car is READY for long periods of time and for lots of time because you're a taxi. The car loves this, as the battery is constantly being balanced.

"Issue with computer system" is vague considering how many "computers" are in the Prius. Get the actual codes.

It sounds like when the mechanic was reading the codes the car was not READY but just IGN-ON and the 12v was flaky. Additionally his scan tool was overpowering communication with the other ECUs. This is completely possible on a CANbus and by design. There seem to be 2 ideologies for scanners. The first is run in the background super low priority. The second is run with a high priority address and block out other traffic. Sounds like the 2nd option is what happened. The car doesn't anticipate a "stranger" on its internal network so this can cause watchdog communication timeouts and then you get errors it couldn't communicate. Which was true at the time. It doesn't know that that is because you have something else hooked up.

I'd clear the codes you have now with a more compatible reader and start looking into replacing the batteries. Both of them. And know that all the lights can (and will) come on at any time. Most likely right after you've picked up an awesome ride with huge surge pricing and then have them abandon you because your car isn't safe with all the dash lights on.
